So have you benchmarked the two? I'd expect select to be faster.
Yup, I have. poll() is faster; copying the parameters takes less time than bit twiddling. > > As for new code, use whichever you are comfortable with.

Whichever you're comfortable with. poll() isn't a pain once you know how to use it, and it does bring additional benefits. -- Jonathan To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
